<h3>
Answer: 7/19</h3>
Explanation:
There are 7 blue marbles out of 4+7+8 = 11+8 = 19 total
The probability of selecting blue is therefore 7/19
We cannot reduce 7/19 any further because 7 and 19 have no common factors other than 1.
Answer:
the banana cost per kg is 6 and for orange it is 4
Step-by-step explanation:
The computation is shown below:
Let us assume the banana be x
And, the oranges be y
Now according to the question
There would be two equations
32x + 86y = 536.......(1)
96x + 52y = 784.........(2)
Now multiply by 3 in equation 1
96x + 258y = 1,608
96x + 52y = 784
258y - 52y = 1608 - 784
206y = 824
y = 4
And, the x would be
32x + 86(4) = 536
32x + 344 = 536
x = 6
Hence, the banana cost per kg is 6 and for orange it is 4
Answer:
What's your fav football team?
Step-by-step explanation:
The simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.
<h3>
What is an expression?</h3>
- An expression or mathematical expression is a finite combination of symbols that is well-formed according to context-dependent norms.
To find the simplified expression:
Given -
- Distance cycled = x² + 7 miles
- Distance ran = 2x miles
- Distance swam = x - 2 miles
Thus,
- Total distance she covers = x² + 7 + 2x + x - 2
- Total distance = x² + 3x + 5 miles
Therefore, the simplified expression that is equivalent to the total distance, in miles, Joy covers is (A) x² + 3x + 5 miles.
